That way there could be an even 5-minute headway Haymarket to Station Road and vice-versa

306 x 20 min
308 x 20 min
309 x 20 min
310 x 20 min (via Hadrian Park)

There are currently 7 buses per hour Blyth to Whitley Bay on Mon-Fri, so reducing to 6 is still a saving (pre covid there were 8 per hour, 4 x 308 and 4 x 309).

310 via Hadrian Park unless during an evening is a big no no. 

GNE giving up Hadrian Park thus 'encouraging' Stagecoach to have the 22 serving Hadrian Park every 20 mins and the other to Cobalt every 20 mins would be the better option. In fact, although it might put the 41/41A at risk with Stagecoach talking some Hadrian Park to Wallsend fares, it would at least protect GNE's 1 from Stagecoach extending the 22 further into North Tyneside.
